Research ArticleOpen accessIn the abstractClimate Change-An Unprecedented Challenge for Humankind Survival; Energy Exploitation from the Atmospheric Electrical CircuitGiovanni Pietro Gregori, Bruce Allen LeybourneA more detailed summary is given in the last part (1/4th) of the Introduction. An anomalous period is in progress, characterized by a very intense release of endogenous energy from the Earth. The cause is an ongoing heartbeat of the Earth’s electrocardiogram. Humankind’s history spans a much shorter duration. Hence, at present the humans are going to face an unprecedented … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 2 Nov 2021 · 6,450 accessesView PDFCite
Research NotesOpen accessIn the abstractTime-Resolution of Climate Change Monitoring Volcanic Cycles, Stromboli, Ocean Floor Biota and Pandemics (?)Giovanni Pietro Gregori, Gabriele PaparoClimate change is an ongoing, poorly understood and disquieting challenge. The primary drivers are debated. Clear evidence is however suggestive of a time variation of the planetary release of endogenous energy. In fact, soil exhalation is an unprecedented challenge for humankind, as a phenomenon of this kind happens only every 27.40.05 Ma, while human history spans only the last 30,0000 … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 Sep 2021 · 6,252 accessesView PDFCite
Research NotesOpen accessIn the abstractOvarian Follicular Dynamics in Caqueteño Creole Cattle Breed at the Colombian Amazon PiedmontLópez-Rojas Robinson, Celis-Parra Gustavo, Tovar-Claros Gilberto et al.Caqueteño creole cattle breed is part of the eight Colombian creole cattle breeds. These breeds are characterized by having great adaptive potential to the environmental conditions in which they are found and allowing them greater productive efficiency. Caqueteño creole cattle is a breed in danger of extinction according to parameters referenced by FAO, since it is a population of cattle … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 3 May 2019 · 8,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuelwood Consumption and its Impact on Forests in the Teknaf Peninsula on the Southern Coast of BangladeshUllah SM Asik, Tani MasakazuThis study focuses on the household fuelwood in the Teknaf Peninsula of Bangladesh. Teknaf Peninsula has a protected forest area which is facing the threat of extinction due to the over dependency of the local people. Among the subsistence activities, harvesting fuelwood from the protected forest area is the most common and also a significant cause for the deforestation. This … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 28 May 2017 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Synthesis of Endangered Frog Alkaloid ’Epibatidine’, A Potent Analgesic of the FutureN.R. Dhatrak, M.G. Kulkarni’Epibatidine’ is a nicotinic alkaloid’, was first discovered in the skin of neotropical poisonous frog, ’Epipedobates tricolor’ found in Ecuador. John Daly in 1974 first isolated a trace quantity of this alkaloid by scarifying several frogs. With the evolution of NMR techniques the structure of this alkaloid was reported in 1992. An year after, Nobel Laureate Prof. E.J. Corey, devised … …Current Research in Drug Discovery, Vol. 1, Issue 2 · 26 Jan 2015 · 17,112 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffect of Doping Position on the Active Silicon-on-Insulator Micro-Ring Resonator Based on Free Carrier InjectionB. Mardiana, Sahbuddin Shaari, P. Susthitha Menon et al.Problem statement: Metal interconnects have become significant limitation on the scaling of CMOS technologies in electronics integrated circuit. Silicon photonics has offers great potential to overcome this critical bottleneck due to the advantages of optical interconnects. Silicon-based optical micro-ring resonator is promising basic element of future electronic-photonic integrated circuits because of its wide applications on photonic devices such as modulator, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 9 Aug 2012 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Predator Go for Size Selection or Preferential Toxic-Nontoxic Species Under Limited Resource?Joydeep Pal, S. Bhattacharya, J. ChattopadhyayProblem statement: Selectivity is common in predator-prey interaction but the selection mechanism is still unexplored and a debatable issue in modern theoretical and experimental ecology for numerous species across the globe. In present investigation we emphasized the hypothesis that the zooplankton is less inclined to opt the food based on size selectivity criteria than the preferential selectivity for the safe … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characteristics of Architecture Style of the Traditional Houses in the Mosul City-Analytical StudyMozahim Mohammed Mustafa, Daizhizhong, Yuan HongProblem statement: Mosul city distinguishes itself in its architecture style which has earned and developed through ages. However, this style is now prone to extinction. This is due to the lack of studies which clarify the characteristics of architecture style in the traditional architecture of the city and benefit from it for future designs and to maintain the architecture identity … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistribution and Determining of Urban Sprawl in Kerman with Emphasis on Kariz Water SystemAli Hosseini, Mohammad Shabanifard, Mostafa Rashidi, Mamohammad Reza SaiydzadeProblem statement: Urban sprawl is one of the contemporary issues of cities all over the world. The Kariz system consists of underground channels that convey water from aquifers in highlands to the surface at lower levels by gravity. The problem of water shortage in arid and semi-arid regions is one of low rainfall and uneven distribution throughout the season, which … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 10,627 accessesView PDFCite
